INTRODUCTION Mr. &Mrs. John and Ruth Tivald are proposing to create four parcels from a 9.24 acre parcel of � land owned by them at 400 Dietrich Road, Linden. The subject property is located north of Copperopolis Road and north of Eastern Heights Road. The Tivald's have produced the Tentative Parcel Map, which is attached, and Mr. John Shoup, L.S. will produce the Final Parcel Map for this project. According to the San Joaquin County Development Title, a Surface and Subsurface Contamination Report (SSCR) is required at the time of Tentative Map submittal. The purpose of this report was to investigate the property for real or potential environmental contamination and report the findings to the Client and the San Joaquin County Environmental Health Department. This report complies with the San Joaquin County Ordinance, specifically 9-905.12 (a) for a Surface and Subsurface Contamination Report. My report addresses and evaluates non-point sources of hazardous materials, as well as potential point sources. Investigated non-point source hazardous materials on the property included agricultural chemical residues from on-site and off-site applications. Non-point sources of hazardous materials were determined to be nonexistent on the subject property, or to be in such low concentrations as to be inconsequential. Point sources of investigated hazardous materials, such as potential hazardous materials containers (e.g., gasoline cans, five gallon containers, and. drums) currently exist. All of these containers were found to be empty, although internal, non- odorous residues may present. Agrichemical storage/mixing areas, as point sources, were nonexistent. It is noted that no chemical analysis was conducted for this investigation, nor was there an inspection of any on-site or surrounding buildings for asbestos containing materials (ACMs). In summary, as of January 20, 2005, which was the date of the last inspection of the property, there appears to be no surface contamination from a release of hazardous materials, chemicals, or other types of environmental concerns. The likelihood of subsurface contamination is almost nil given the historical use, and current length of known ownership of the property. However, there is a substantial number of non-hazardous items, such as fuel and oil containers, old automobiles/ farm implements, tires, etc., on the property. These items are in the process of being removed by the Tivald's and taken to recycling facilities, to disposal facilities (if applicable), or being sold to scavengers or collectors. The number of tires transported for any one trip will not exceed nine. Consequently, in accordance with San Joaquin County Ordinance 9-905.12 (c), it is my opinion that the only corrective action required for the property, is to continue the removal of the aforementioned items from the property under proper disposition or disposal.
